This reminds me of the stories I'd hear about General Braddock's Battle for Monongahela and his buried Gold treasure from . Supposedly it's somewhere down in the river valley where I grew up near Kennywood Park in PA.

"Before setting out to attack Fort Duquesne, Braddock decided that the King's gold the column was carrying as payroll for the officers and men should be buried to prevent it from falling into the hands of the French. It could then be recovered after the battle was won.

Braddock ordered the scouts to retrace their trail to Youghiogheny River and cache the gold there. This they did, following Crawford Run to the river and burying the cache of gold coins under a walnut tree. After burying the gold, the scouts departed to rejoin Braddock's column."
